The Questionable Authority: How many species 2: What is a species, and Why does it matter?:
The reason that we have a hard time coming up with a definition of species that works for everything is that there isn't one. Different types of organism keep themselves sorted out in groups in different ways. Mayr's definition works (at least in theory) for organims that are sexually reproducing. It goes all to hell when confronted with asexual organisms, and it gets worse when you toss plants into the mix - they do the wierdist damn things as they evolve.(Go read John Wilkins' paper on the topic, since he does a much better job explaining this.) Because evolution is an active, ongoing process, you will also find - no matter what definition works best for your organisms - some groups that are pushing the boundaries between species.

It's a tired analogy, I know, but dealing with "species" really is a lot like dealing with the concepts of "child" and "adult." We know that there are differences between children and adults. It takes no real insight to look at the two and identify significant distinctions between the groups. The problem comes when you try to come up with definitions of "child" and "adult" that are capable of unequivocally distinguishing the two. It can't be done - there is no sharp distinction between the two there to identify.
why, God, why?

And that Yahoo thought it was so important it put it on the front page of my.yahoo.com as an absolutely vital to know Top Story?
